A childhood belief about getting pregnant

I was a reader when I was young and we had these old kids' books full of facts that I loved to read. One was "All About the Human Body" and it explained eggs, sperm, and fertilization. There were also anatomical diagrams I didn't understand, but the books were from the 50s so they were too conservative to explain anything more. So I knew sperm from the man's body had to somehow get into the woman's body for there to be a baby. When I asked my mom about this subject, she used to say it was "a special kind of love" between two people. So I thought that after two people fell in love and got married, they would walk down the street (or something), and the sides of their bodies would touch while they were walking. The sperm would somehow pass through their skin from the man to the woman, and then she would get pregnant. The funniest thing is that I imagined all this taking place with their clothes on because it literally never occurred to me they might take them off in front of each other.
